Hallo.habe bought the thing because it has promised me most of the recessions. Delivery was prompt and fine. Only I would have expected a little more. Lying down your own body weight pressed too much on the mat, so that the massage balls over it rumbling relentlessly across shoulder blades and in the cross one is but naturally not on, so you, in turn, does not feel much. Now I have to lie on the couch as a cushion and here it is a little better, because you can not plan pushes her back so. I especially like it now in the cross because they drübermassiert here perfectly smoothly. In the upper shoulder area, the mat failed but because they simply no longer rankommt here. They massaged practically the air field. A pity is that there is only one spot function and not a "function area" where I can even set the scope. (From the device itself, you can choose only between upper U. Lower back where above then it is only a small part is massaged, because the rest yes hangs in the air). Therefore, because of the value for money only 2 stars.
